I'm glad you're not thinking of transitioning. Not because you'd be "bad" or "wrong" if you did, just that it would likely not solve the problems you already have and would give you new problems (and medical bills) on top of what you already deal with. Have you ever seen the detrans subsaidit or subreddit? Might be worth a peek if you haven't.

There's been good advice given here already, and I'll add something: Nutrition. Not expensive bro-science supplements or woo-woo stuff, but make sure you're getting enough vitamin D, whether it's from D3 tablets, sunlight, or your food. B vitamins can play a role too. Like any science, the science on this is evolving as more studies are done and more data is collected, but here's an example.

Ever heard of dialectical behavioral therapy (DBT)? It was started to help treat people with borderline personality disorder, but the skills it teaches can help people that are nowhere near borderline but are struggling with other aspects of their mental health. This site isn't the prettiest, but it's a start. Mindfulness, distress tolerance, emotional regulation, and interpersonal effectiveness are the core skills taught.

Getting things done helps lift my mood. It doesn't have to be everything at once. Throw out some trash, dust a few things, clean the bathroom sink. One thing at a time. Helps me feel less overwhelmed, less "useless" or "lazy" when I get into self-critical moods.

I hope this doesn't all sound like "wow, thanks, I'm cured." It's more about staying on top of the anxiety and depression and managing them so you can focus on other things and not feel so swamped and hopeless. Please don't give up on yourself. You deserve more happiness and a better life, and I believe you can get there. One step at a time.
